ACTT8-800C0Q

Overview

The ACTT8X-800C0Q is a bidirectional thyristor (triac) manufactured by WeEn Semiconductors, designed for AC power switching applications. It features an RMS on-state current of 8 A and supports non-repetitive peak on-state currents up to 80 A. The device offers a rated repetitive off-state voltage of 800 V with a maximum on-state voltage of 1.3 V. Gate triggering requirements include a maximum gate trigger voltage of 800 mV and a gate trigger current of 30 mA. The component operates within a temperature range of -40 °C to +125 °C and utilizes a TO-220F-3 through-hole package.

Procurement Notes

Verify the exact part number against official manufacturer documentation, as suffixes may indicate specific packaging or compliance variations. Confirm RoHS status and lead times directly with authorized distributors or the manufacturer. Ensure that the ordering information matches the required electrical specifications and package type for your design implementation.

Selection Notes

Select this component when an 8 A RMS current rating and 800 V blocking voltage are required in a through-hole configuration. Consider the 1.3 V on-state voltage for thermal management calculations. Verify that the gate trigger characteristics align with the driving circuit capabilities. Ensure the operating temperature range meets the environmental requirements of the target application.

Part Context

This triac belongs to the ACTT series from WeEn Semiconductors, which focuses on high-performance AC power switches. The series is characterized by planar passivation technology for reliability. Similar parts in the lineup vary primarily in current ratings and package types, such as surface-mount D2PAK variants or different current capacities within the same voltage class.

Replacement Considerations

Compatible substitutes include the BTA308X-800C0/L03Q, which shares similar electrical characteristics but differs in holding current and maximum junction temperature. Other alternatives within the ACTT family should be evaluated based on matching RMS current, voltage ratings, and package compatibility.
